As a budding data analyst, my passion is to find efficient solutions and solve problems that may arise. Sometimes, however, life does not let you find immediate solutions. In those instances, I prefer to gather as much data as possible, summarize my findings, and analyze the data to see what can be learned to better equip me in the future.

ABOUT ME
Hi, my name is Chris, an aspiring data analyst. I hold a Bachelor's degree in Political Science, a diploma in Electromechanical Engineering Technician, and multiple Data Analyst related Certificates (UofT SCS Data Analytics Bootcamp, Google Data Analytics Professional Certificate, SQL - MySQL for Data Analytics and Business Intelligence from Udemy)
I have always enjoyed solving puzzles as challenges. I like to continually look for more efficient and comprehensive methods to solve different problems and further improve my skills and understanding of data science. Being exposed to the world of data analytics has allowed me to know and become a part of the advanced modern-day problem-solving process, and I am eagerly looking for new challenges to broaden my knowledge base.
If you think we will work great together, please reach out to me by email.
